Text Does Not Get Recognized Properly
Try these solutions if any part of the original document is not converted
to text properly during OCR:
• Look at the original page image and make sure that all text areas
are enclosed by text zones. If an area is not enclosed by a zone, it
is ignored during OCR. See “Creating Zones for OCR” on page
26 for more information.
• Make sure text zones are identified correctly. Alphanumeric text
zones are marked by an
A
. Graphic zones are marked by a
G
.
Reidentify zones, if necessary, and perform OCR on the
document again. See “Changing Zone Properties” on page 71 for
more information.
• Make sure the correct main and secondary document languages
are selected in the
Language
settings. Only languages included in
the document should be selected. See “Language Settings” on
page 50 for more information.
• Select
Use Language Analyst
in the
Accuracy
settings. The
Language Analyst evaluates words and corrects likely errors
during OCR. See “Accuracy Settings” on page 49 for more
information.
• Train OmniPage Pro to recognize special characters that might
normally be difficult to recognize, such as the copyright symbol
© or the registered trademark symbol ®. See “Training OCR for
Special Characters” on page 74 for more information.
• If you use
True Page
as the
Output Format
setting, recognized text
gets put into frames (formatting boxes) in the text viewer. Some
text may be hidden from view if a frame is too small. To view the
text, place the cursor in the text frame and use the arrow keys on
your keyboard to scroll to the top, bottom, left, or right of the
frame.
• Check the glass, mirrors, and lenses on your scanner for dust,
smudges, or scratches. Clean if necessary.
OmniPage Pro only recognizes printed text characters such as
typewritten or laser-printed text. However, it can retain handwritten
text, such as a signature, as a graphic. See “Do you want to retain
graphics in your document?” on page 60 for guidelines on retaining
graphics.
